Tak, długość tego kabla jest krytyczna:
"Broadband pi-network circuits couple the exciting signal into the cathode circuits of the power amplifier tubes. In conjunction with the interconnecting r-f feed cable supplied, this presents a nearly constant 50-ohm load to the exciter This aids in maintaining the low level of distortion products under modulation. For this reason, it is important not to alter the length of interconnecting cable supplied with the amplifier."
